BEA'IING APPARATUS.

Application filed May 22,

To all whom itmay concern: 1

Be it known that I, STANLEY J. J EM- BRZYCKI, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Beating Apparatus, of which the following is a specification.

My invention relates to beating apparatus adapted particularly for kitchen use for beating eggs, cream, etc.

One of the important objects of my invention is to provide a unitary reduction gearing structure which can be readily and detachably applied to the rotatable beater blade structure or cage, and to provide a simple, flexible and detachable connection between the gearing structure and the driving motor, preferably electric. Another important object of the invention is to provide means for keeping the motor and container in alignment and to prevent tilting or tipping of the container when the motor is running. Another important object is to provide such construction and arrangement that the gearing structure can be readily with drawn from the container and beater frame, and the frame withdrawn from the con tainer so that the parts can be readily cleaned and the appartus kept in sanitary condition.

The above and other features of my invention are incorporated in the apparatus illustrated in the accompanying drawing, in which Fig. 1 is a side elevational view of the apparatus with the gearing structure partly in section, and

v Fig. 2 is a sectional view on plane 2-2, Fig 1, and with part of the motor structure broken away to better show the alignment mechanism.

On the drawing 5 represents the container which is constructed of sheet metal and supported on legs 6 which may be suitably formed up of sheet metal and soldered to the container. The lower part of the container is semi-cylindrical and within the container is the beater structure comprising end frames 7 and 8 and sets of beater wires, a, Z) and 0, extending from the frames at spaced intervals. The beater wires are of U shape and soldered at their ends to the end frames, the longitudinal sections of the wires being 1922. Serial No. 562,616.

offset radially as shown in order to give better beating service. The beater is supported on the shaft 9, which shaft is detachable. The inner end 10 of the shaft has bearing in the deflected part 11 of the adjacent side wall of the container while the outer end of the shaft extends through the hole 12 in the opposite wall of the container, the wall being flanged out as indicated at 13 to afford better bearing surface for the shaft. Adjacent its inner end the shaft has the threaded section let for threadedly receiving the end wall 7 of the beater structure, while the end wall 8 has the opening 15 through which the shaft extends.

At its outer end the shaft 9 extends into the gearing structure designated as a whole by G. The housing 16 of the gearing structure has the chamber 17 containing the worm wheel 18 which is secured on the shaft end as by means of the pin 19. Outside of the worm wheel the shaft journals in the lugs 21') formed on the outer wall of the housing, while inside of the wheel the shaft journals in the cover 21 which is detachably secured to the housing body by screws 21. Below the worm wheel is the horizontal worm shaft 22 journaled at its one end in the lug 23 and bearing at its other end in the lug 2 1. Be tween the bearing lugs the shaft supports the worm 25 which meshes with the worm wheel. The end of the worm shaft extends into the cylindrical inlet passageway 26 and has the bore 27 for receiving the end of the drive shaft 28 extending from the armature of the motor M. The bored end has the slot 29 for receiving the tongue 30 on the shaft 28. The shaft is flexible and extends through the supporting cap 31 on the motor and the coupling tip 32, which tip is connected with the cap 31 by the flexible tube 33. The end of the coupling tip has the peripheral groove 34 for engaging in the passageway 36, a latch ball 35 being yieldably held in the groove by the spring 36 which is pressed down by the screw 87 which threads in the housing 16, lVhen the motor is to be attached to the beater the coupling tip is inserted in the passageway 26 until the latch ball engages in the groove 3 1 the end of the shaft 28 then engaging in the end of the worm shaft 22 with its tongue 30 in the slot 29, coupling being then established and the worm shaft being rotated when the motor is in operation.

To keep the motor in alignment with the beater container and to prevent tilting or tipping of the container when the motor is in operation I provide an aligning and looking rod 38 which extends through the lug 39 provided on the supporting base structure of the motor as shown in Fig. 2, a lock screw 10 being provided to hold the rod in adjusted position. The rod is provided with the head ll by means of which it can be readily shifted and the outer end of the rod extends through the adjacent leg 6 of the container, a thimble 42 being preferably provided on the legs to give greater engagement surface for the rod. After the rod has been shifted through the thimble and securelyloclzed by the screw ll) the motor and container will keep their alignment and the container connot tilt when the contents thereinbecome of a consistency to offer greater resistance to the rotation of the beater structure. By means of the reduction gearing the beater structure is powerfully rotated and the speed of rotation can be further controlled by means of the switch lever 43 which controls a rheostat (not shown) in the base of the motor.

After the container contents have been properly be ten and it is desired to remove the contents or to clean the parts, the motor disconnected, the beater frame held against rotation, and the gearing housing bodily turned to unscrew the shaft from the end wall 7 of the beater structure. The gear- 'ing housing together with the shaft can then be withdrawn and the beater structure can be lifted out ofthe container. The parts can then be readily cleaned. To put the apparatus in condition for operation the beater structure is inserted in the container and the shaft is inserted and turned by means of the gearing structure until it has been threadedly secured to the end wall 7 and its end 10 'received'in the bearing deflection 11. The motor is then attached and the aligning rod 38 is secured.

I thus produce a simple apparatus whose parts can be readily connected or disconnected and which can be readily cleaned and kept in sanitary condition. I do not desire to be limited to the exact construction and arrangement shown as changes are possible which would come within the scope of the appended claims.

I claim as follows:
